Material prices below are national averages; availability in Nashville may shift costs slightly.

Material	Cost/Unit	Pros	Cons	Best For
PEX Tubing (Standard)	$0.50-$1.00/linear ft	Flexible, corrosion-resistant, easy to route, 50+ year lifespan	Cannot be exposed to UV light, needs proper oxygen barrier	Most residential hydronic radiant installationsFlexible, corrosion-resistant, easy to route, 50+ year lifespan
PEX-AL-PEX (Aluminum Layer)	$1.00-$2.00/linear ft	Holds shape after bending, built-in oxygen barrier, lower expansion	More expensive, less flexible than standard PEX, fewer fitting options	Tight routing situations and high-oxygen-sensitivity systemsHolds shape after bending, built-in oxygen barrier, lower expansion
Thin-Slab Overpour (Gypcrete)	$3-$6/sq ft installed	Excellent thermal mass, even heat distribution, quiet	Adds 1-1.5 inches of floor height, heavy, longer cure time	New construction or major renovations where floor height change is acceptableExcellent thermal mass, even heat distribution, quiet
Aluminum Transfer Plates (Staple-Up)	$2-$4/sq ft	No floor height change, works from below, faster install	Slightly less even heating, requires accessible floor joists	Retrofits with accessible basements or crawlspacesNo floor height change, works from below, faster install
